Loose-nner BINDER Application :filled May 214, 1,922. Serial No.563,282.

T all whom t may concer/n:

Be it known that l, JOHN J. POTT, a citi- Zen of the United States, andresiding at St. Louis, Missouri, have invented the new and 5 usefulImprovement in ,Loose-Leaf Binders,

of which the following isa specification.

This invent-ion relates to loose lea-f binders employed Vfor holdingsheets orleaves-teinporarily` in book form and constitutes animprovement on the loose leaf binder of Patent No. 1,184,01e, patentedMay 23, 1916.

lOne of the objects of this invention is to provide a loose Aleaf binderarranged to holdy the leaves or sheets so as to permit manipulation,removal and replacement ofthe same.

Another object of this invention is to provide a loose leaf binder whichis arranged to selectively hold the sheets eitherso as to permit them tobe turned from onel back to) another or to hold .them on lone back ofthebinder.

Another object of :this invention is to providea loose leafibixnderwhich is simple in construction, effective in its action and cheap tomanufacture.

Further objects will appear from the detail description taken inconnection with the accompanying drawing, in which:

Figure l is a perspective view of a binder Vembodying this invention;

Figure 2 is a section, Lsomewhat enlarged, on the line 2-2, Figure l; n

Figure 3 is a View similar to Figure 2, but showing the employment of aholding head; and

Figure 4; is a still further enlarged detail of Figure 2.

Figure 5 is an enlarged detail of Figure 2 showing the fastening of thethreaded post.

Referring to the accompanying drawing,

the binder, as shown, comprises a back l havling sides 2 of paper boardor any other suitable material and provided with a covering 3 which maybe of fabric, leather or any other suitable material, this coveringalsoforming the hinge connections 4.

Incorporated in one of the sides of the back are a base strip 5 of metalor any other suitable material, which extends laterally along the innerface of the side and is turned under as shown at 6. These strips arepressed or sunk into the back and are covered by the covering 3, so asto present a neat and attractive appearance. Secured rated as shown at1;()v while theback beneath this perforation is also yperforated butsomewhat enlarged as shown at 1l. 'There is, therefore, provided arimmedsocket providing a ledge or rim. i

A pair of arches 12 are `constructed of a resilient metal, such assteel, and one leg 13 of this arch is shortened'and reduced .-'toprovide a shank adapted to take .finto the hollow post 7 and 4provide a'shoulder ar ranged' to rest ontheend of thepost. The other long leg ofthe arch is reduced to `provide `afti'pV rearranged to enter the socket,and this `tip `is notched on Lone side away from the support of the archon the post 7, so as to engage with the rim of the socket, while ashoulder is provided at the end of the arch leg.

The arch is so formed that when in posi-` tion on the post, it willnormally be in position as shown in dotted lines, Figure 2, so that thetip extends over but beyond the socket. By, however, springing the longleg towards the post and the back, the tip can be Asprung into thesocket until its notch takes into the rim of the socket in the strip 5,when the arch will be firmly held in position. The end of the tip can berounded as shown so that the tip can be snapped into the socket by abearing and springing pressure applied to the arch. The arch itself ispreferably resilient enough to permit such springing; however, themounting of the post on the strip 5 is such that this post and strip canspring to permit such engagement. This strip provides a firmsupportingbase with the arch, its post and socket, so as to provide astiff back base. It will, of course, be understood that the arch tip can`be disentgaged from the socket by a reverse movement thereof as will bereadily understood. The shoulder 8 as well as the other metal parts arecovered by the covering 3 so as to conceal all metal base parts andpresent a neat and attractive appearance.

rIhe provision of the arch permits the leaves l5, which are perforatedfor that pur pose, to be not only retained in the back of the binder,but also permits them to be turned over the arch and on the other leg,as required. ln some cases, however, this arch is not required Where,for instance. the leaves are only to be held on one or the sides of theback. Accordingly the post 'i' is threaded to receive the threaded shank16 of a knul-led head 17. Accordingly by removal oi the arches, thelatter can be replaced by the retaining` heads 17 and vice versa. ltwill, oi course, be understood that the shanks 13 of the arches aresmooth and oi" suliciently small diameter to permit these shanks to bereadily slipped into the thread-- ed posts.

lt will, therefore, be seen that the invention accomplishes its objects.A hinder is provided which is not only simple in construction, buteffect-ive in its action and cheap to manufacture. rlhe interchangeableapplication of the arch or the retaining head permits this binder to beused for va ried purposes. The retaining means for the leaves is notonly rigid and strong, but the base is entirely concealed, so as topresent a neat and attractive appearance.

lt is obvious that various changes may be made in details otconstruction Without departing trom the spirit of this invention; it is,therefore, to be understood that this invention is not to be limited tothe specific details shown and described.

Having thus described the invention, what is claimed is:

l. A loose-leaf binder comprising, a back provided with a base striphaving a socket, a post on said strip, and an arch having one legcooperating` With said post and having its other leg formed to be sprunginto retaining engagement with said socket by springing said arch.

Q. A loose-leaf binder comprising, a back provided With base striphaving a socket, a post on said strip, and an arch one or" whose legshas a bearing in said post and Whose other leg is formed to be sprunginto retaining engagement With said socket by springing said arch.

3. A loose leaf binder comprising, a base provided with a socket, a poston said base adapted to receive a retaining head, and an arch adapted toconnect With said post and having a tip adapted to engage said socket.

il. A loose leaf binder comprising, a base provided With a socket, athreaded post on said base adapted to receive a threaded retaining head,and an arch adapted to connect with said post and having a tip adaptedto engage said socket.
